The tuner is great and very accurate, but there is no sound when I click on the “start” button for the metronome. ### 4/5 — It’s ok *2019-10-24* This app is great but most of the time the metronome doesn’t work and I like that you can change the emoji that shows up but you guys need to focus more about the thing your app has ### 3/5 — Disappointed 😢 *2018-09-09* Was looking forward to using this app. It doesn’t seem to do all of it’s basic functions: tone does change, but all the metronome does is stop the tone and tapping only changes the numerals - never a peep from the speaker 🤐😪. I really wanted this to work!! Please, fix the bug(s) soon. I’m sure many of us will be very pleased with that. Thanks C 🎻🌵 ### 5/5 — Amazing!!!!! *2018-02-19* This app is absolutely wonderful to have! I play oboe and this helps me tune so easily and keeping the tempo of the piece I'm playing is no problem! ### 3/5 — overall *2017-11-26* overall, the tuner is great! it helps me tune easily and efficiently without needing to buy a tuner. the toner helps me with other instruments such as flute and trumpet! it helps a lot. like how it is free instead of needing to buy one as well! a negative response is that the metronome does not work. i put up my volume on my phone many times but there is no sound coming out. can you guys please fix it because that is my main concern! thank you! ### 4/5 — Best tuner out there except for one thing *2017-10-03* I love this app because I use it everyday when I practice. It is super helpful. HOWEVER, the metronome does not work. There isn’t a sound produced once you click start. I tried adjusting my phones volume but it didn’t work. Please fix this. Once this is fixed I will change my rating to 5 stars. ### 5/5 — Great app!!! *2017-05-05* Works great and simple! Please add a widget feature. I would gladly pay for a widget! Can you allow this app to work with wireless headphones? ### 5/5 — Amazing!!!!! *2017-03-01* It's a simple app with a clean layout and it's easy to use. Probably one of the best free tuner/metronome apps out there. ### 5/5 — Wonderful! *2017-01-24* Couldn't ask for a more useful app! Great for practicing pitch matching, as it will tell you exactly whether you're sharp or flat, and by how much. No annoying ads or constant "rate us" pop ups, either. Love it! ### 5/5 — I love it *2017-01-21* It's so great I use it for everything!! ## Frequently asked questions about Treble ### What instruments can Treble tune?
